summary To model a database that stores geo-indexed data or space, a diversity of models exists in the literature. In this article the models will be studied proposed by Michael F. Worboys, Peter Milne and S. A. Roberts and will be represented using OMT (Object Modelling Technique) of Rumbaugh. The models will be evaluated following a methodology based on the existence of a ideal model of reference against the one which to be able to contrast them. The created ideal pattern will be constituted in a new model for the design of space databases OxO.

title Physically Based Daylight Simulation and Visualization
source Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 406-407
summary While architects typically agree that daylight is a powerful influence for design, architects rarely collect and use daylighting data to help make informed design decisions. This deficiency exists partially because there are no common tools available to provide useful and accessible data. The objective of this project is to provide accurate daylighting data of a prominent urban building site and present it in a clear way so that the architects can make well informed design decisions that respond to site daylighting conditions and improve architectural performance. An urban 3D computer model was created with AutoCad, a commercial CAD application. Daylight was simulated with Radiance, the physically based rendering engine developed at Lawrence Berkeley National Laboratory. The standard CIE model for clear sky and sun was used to produce over 500 images that represent daylight conditions for three different times of year at 10 minute intervals in both luminance and illuminance formats. The simulation data was packaged for analysis with a unique browser tool that enables the architect to easily cycle through the data to evaluate and compare behavior by time of day and by season. The architect can also toggle between luminance and illuminance format to easily visualize both qualitative and quantitative data. The exploration and use of the simulation data can be applied with sensitivity to inform the design and decision making process for the exterior building site.

title Hitchhiking through a Maze of Transformations and Filters with a Bag of Data
source International Conference on Generative Art
summary The disappearance of plotters as peripheral devices makes it necessary to explore alternative output devices like printers for the generation of art work, based on lines and HPGL-code. The findings are frustrating and the conclusion drawn is somewhat devastating: abandon all hope,write new programs to fully take advantage of the printing age. Plot as long as the old hard- and software is still working.

source Automation in Construction 10 (2) (2001) pp. 239-246
summary The great advance in information technologies (IT) and the availability of a wide range of software in recent years have brought many changes in the construction industry. The Internet, a new member of IT, offers a medium with new opportunities to manage construction projects. This paper describes an Internet-based project management system called "Total Information Transfer System" (TITS). TITS comprises six major functions including data exchange, information exchange, Internet chat, live video-cam, search engine and auxiliary services. TITS is demonstrated for project monitoring with a real-life project.

title Communicating Generic Process – Some Issues of Representation Related to Architectural Design
source International Conference on Generative Art
summary It is commonly the intent of an architect to represent the development of an idea from the early sketches to the final artefact, as well as to explain particular functions of its parts or complex construction processes. But the opening of the secret of generic process to the public - presenting a range of possibilities instead of one final solution and even involving external participants in the creation process - is brand new. The contemporary communication of architectural ideas presumes both – visual/formal representation and interaction. As a result of research in the field of communication in architecture, this paper is focused ongeneric process phenomena, in particular on issues of its representation. It is based on analysis of a wide range of examples that have appeared in recent years, either in electronic, printed or physical form. It offers a systematization of approaches to representation and discusses thepotential and limitations of each type – series of physical objects, sequences of graphics (single, linear, planar and spatial) and animation, as well as their combinations (sequences of animations). A particular emphasis is placed on increasing the functionality of sequence-basedrepresentation (interacting, navigating…) and its interdependence with animation as a special case. Finally, the author proposes a rethinking of the role of both the architect, who defines a system of possibilities rather than a single solution, and the information recipient, who becomes not merely a passive spectator, but a creative participant in the design process.

source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 161-172
summary This paper describes VR Sketchpad, a pen-based computing environment for inputting and locating 3D objects in a virtual world. Designer can use the transparency layers to quickly trace and extract any image underlay from other application software. The 3D scene generation has three levels of complexity: simple extrusion of any drawn lines of shapes (i.e., straight or curved wall and column extrusion), solid modelling from a given geometric object representation (spheres, cones and boxes), and complex configuration with objects from graphics library (furniture layout).

title Augmented Reality Techniques for Design and Revitalisation in Existing Built Environments

summary Building activity in Germany is moving increasingly toward combined newbuild and renovation projects. Essential for effective computer-aided planning within an existing context is not only the use of on-site computer-aided measurement tools but also an integrative cooperation between the different disciplines involved via an information and communication system. Interdisciplinary cooperation needs to be tailored to the integrative aspects in renovation and revitalisation work. Economic factors determine the viability of an architectural project, and reliable costing information is vital. Existing IT-approaches to this problem are not yet sufficiently exploited. In ongoing research at our university (collaborative research center ”Materials and Structure in the Revitalisation of Buildings”) methods and techniques of revitalisation are being investigated. A special branch of the collaborative research center is investigating possibilities of computer-aided building measurement and communication platforms for professional disciplines (www.uni-weimar.de/sfb). The aim is to develop a general approach to the revitalisation of buildings. This paper discusses possible application areas of AR/VR techniques in the revitalisation of buildings from the point of view of the user and are based on the real project “Cooling factory Gera”. Based on the necessities of revitalisation projects, technical requirements are developed. The project is funded by the Deutsche Forschungsgesellschaft (DFG).

title Customizing mass housing: a discursive grammar for Siza’s Malagueira houses
source PhD dissertation, Department of Architecture, Massachusetts Institute of Technology, Cambridge, Mass
summary This thesis proposes a process of providing mass-customized housing based on computer-aided design and production systems. It focuses on the design part, which mainly consists of an interactive system for the generation of design solutions based on a mathematical model called discursive grammar. A discursive grammar includes a shape grammar, a description grammar, and a set of heuristics. The shape grammar provides the rules of formal composition, whereas the description grammar describes the design from other relevant viewpoints. The set of heuristics is used to guide the generation of designs by comparing the description of the evolving design with the description of the desired house. The generation of a design proceeds first by producing a design brief from the user-prompted requirements and then by finding a solution that satisfies this brief. Search is largely deterministic, which decreases the amount of time required to find a solution, thereby making it reasonable to develop Web-based implementations. The proposed model enables an enduring designer's dream, that of the mass customization of housing. The model is illustrated with a case study that includes a shape grammar developed for the houses designed by the architect Alvaro Siza at Malagueira, a description grammar based on the Portuguese housing regulations, and a set of heuristics inferred after a set of experiments. In these experiments, designers were asked to generate houses based on the Malagueira grammar for specific clients. It is argued that this discursive grammar provides a rigorous method for understanding and teaching Siza's design process and that similar grammars could be developed for other styles. A Web page for explaining the grammar and generating new designs on-line was developed as a prototype.

title Quantifying the Qualitative Design Aspects
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 111-116
summary Architecture is a mixture of art and technique. This implies that the architect deals not only with engineering aspects that can be easily quantified and thereafter processed, but deals with aesthetics as well which is in first place qualitative and therefore rather difficult to estimate and numerically represent. As an example, in such cases, these ‘qualitative quantities’ are expressed in linguistic form which should be somehow expressed in numerical form in order to treat such data by powerful and conclusive numerical analysis methods. Expressions such as: bright colour, light room, large space are some of these examples. These expressions are fuzzy concepts whose actual interpretation is hidden and all of them together attach a qualitative value to a certain space. To deal with such information the emerging technologies of the last decade can provide an important aid. One of them is the soft computing technology that can deal with such soft data. In this paper, based on the case studies, we explain the potential of using soft computing techniques.

source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 460-465
summary We describe a constraint-based three-dimensional design environment called Smart Objects. In Smart Objects, design collaborators (designers, clients and consultants) would engage an architectural design in an interactive three-dimensional environment where they may alter objects in the model and compose formal solutions. Design intentions embedded into objects as constraints are expressed as behaviors when the user moves objects in ways that either violate or meet specified constraints.

title Smart Objects: Constraints and Behaviors in a Dimensional Design
source University of Washington, Design Machine Group
summary Each new design problem in architecture presents a new set of requirements .A designer must remain aware of these requirements and effectively communicate them to collaborators because the degree to which the requirements are met will determine the success of the solution. This thesis explores how design can be effectively presented in a medium that is both explorative of form and descriptive of the design problem’s requirements. To facilitate this, we present Smart Objects, a constraint-based three-dimensional(3D) computer program. In Smart Objects, design intentions of an architectural problem are embedded as constraints into the modeled objects that compose a formal solution. A model is presented through a 3DVirtual Reality Modeling Language (VRML) viewer and constrained by a software program we wrote in the Java language. Both the VRML viewer and the Java program are contained within a single web page. In Smart Objectsd. A designer meets or violates constraints, objects behave in a manner that reflects the requirements of the problem and intentions of the designer. SmartObjects communicates the design principles and guidelines that inform an architectural design to the collaborators involved in the project. It ensures that these principles and guidelines are maintained as the design progresses.

summary Architects manage not only information about the building but also about the user organisation. Therefore, information systems for architectural design must be able to handle both building and organisational data. The paper describes architectural design as a creative problem solving process, and presents a recently developed prototype application for user activity modelling built as an add-on to ArchiCAD.

summary In the last 18 months, students from the Institute for Industrial Building Production (ifib) have undertaken six design projects as so-called Netzentwurf (“Net- Design”) studios in collaboration with different universities in Europe. These studios have used a web-based collaboration platform established at an independent web site and use didactical methods for web based design collaboration established over the past four years at ifib. A total of some 500 students have been involved in these projects and all have used the common platform to carry out their presentation and communication work.

title Qualitative Spatial Reasoning Based on Algebraic Topology
source J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary Several formalisms have been proposed for qualitativereasoning about regions and their topological relations in space. Theseformalisms, based on pairwise relations, do not allow sufficientlypowerful inferences to be used for spatial reasoning tasks such asplanning a collision-free path. In this paper, I show how consideringrelations between region triples, much more powerful reasoningtechniques become possible. I show in particular that in twodimensions, purely topological reasoning is sufficient to compute aminimal place graph which represents all minimal and maximal regioncombinations, as well as all minimal paths between them. I illustratehow this could be applied to motion planning, showing that in spite ofits qualitative nature, the formalism is powerful enough to solveproblems of practical interest.

source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 500-504
summary Some applications of hypermedia technology we developed trough the years to represent urban environment are reviewed. From the results the need for a change of paradigm rises. The strategy for a new system to develop is exposed, based on the assumption that: – the information does not pre-exist its representation; -– the process of cooperatively and competitively represent a situation causes its changing in the same time. -– no single actor will be able to represent the territory in its complexity; The question we need to answer is not what kind of technology we need to manage the information we have but the opposite: what kind of information we need for the technology we have. This information is not neutral nor automatically generalisable, thus, to implement a content based approach, a new system will be designed during a urban developing project.

title PCIS Revisited: A Visual Database for Design and Construction

summary This paper presents research on a piece-based construction information system called PCIS(pronounced “pieces”) first published as a visual information concept at ACADIA’96, Tucson. After more than five years of development it has evolved into a multidimensional visual information system for design and construction. It includes a piece-based anatomical construction model layered according to a work breakdown structure; a dataTheater that surrounds the model as an index to plans, elevations, sections, and details; and a dataWorld with cameras fixed to the intersections of its latitudes and longitudes to add context and perspective. A standard services matrix (SSM) controls layer visibility and camera settings. PCIS can be “played” to access archived resources; support design development, analyze and resolve preconstruction conflicts, and coordinate construction activities. Current research will be used to demonstrate how PCIS might be valuable to increase the potential for technical cooperation, collaboration, and communication by literally aligning the points of view of architectural, engineering, and construction methodology.
